Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

| Name | MARCHF1 (HGNC:26077) |
|---|---|
| Synonyms | MARCH1, RNF171 |
| Function | E3 ubiquitin-protein ligase that mediates ubiquitination of TFRC, CD86, FAS and MHC class II proteins, such as HLA-DR alpha and beta, and promotes their subsequent endocytosis and sorting to lysosomes via multivesicular bodies. By constitutively ubiquitinating MHC class II proteins in immature dendritic cells, down-regulates their cell surface localization thus sequestering them in the intracellular endosomal system. |
| Cellular Location | Golgi apparatus, trans-Golgi network membrane {ECO:0000250|UniProtKB:Q6NZQ8}; Multi-pass membrane protein. Lysosome membrane; Multi- pass membrane protein. Cytoplasmic vesicle membrane; Multi-pass membrane protein. Late endosome membrane; Multi-pass membrane protein. Early endosome membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein |
| Tissue Location | Expressed in antigen presenting cells, APCs, located in lymph nodes and spleen. Also expressed in lung. Expression is high in follicular B-cells, moderate in dendritic cells and low in splenic T-cells. |

Background
MARCH1 is a member of the MARCH family of membrane-boundE3 ubiquitin ligases (EC 6.3.2.19). MARCH proteins add ubiquitin(see MIM 191339) to target lysines in substrate proteins, therebysignaling their vesicular transport between membrane compartments.MARCH1 downregulates the surface expression of majorhistocompatibility complex (MHC) class II molecules (see MIM142880) and other glycoproteins by directing them to the lateendosomal/lysosomal compartment (Bartee et al., 2004 [PubMed14722266]; Thibodeau et al., 2008 [PubMed 18389477]; De Gassart etal., 2008 [PubMed 18305173]).
